Abstract

An optical fiber comprises a light-guiding glass fiber and a coating around the glass fiber. The coating consists of at least two layers of polyorganosiloxane resin compositions having a ladder portion and a linear portion.
The ratio of the ladder portion to the linear portion in one layer (the outer layer) is different from (smaller than) that in the other layer (the inner layer). The resulting fiber has improved strength and thermal resistance.
